ROTARY ENG IN E.

SPECIFICATION forming part of Letters Patent No. 399,952, dated March 19, 1889.

Application filed April 16, 1883- Serial No. 270,775- (No lln'Jdel.)

.To 0, whom it may concern.-

' Be it known that 1, CHARLES WARD, jeweler, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a certain new and Improved Rotary Engine, of which the following is a specification.

The object of the invention is to design a simply-constructed rotary engine in which all the working parts are arranged so that they will not leak steam, and in which the full effective power of the steam is secured; and it consists in the peculiar combinations and the construction, arrangement, and adaptation of parts, all as more fully hereinafter de scribed and claimed.

Figure 1 is a perspective view of my improved rotary engine, having a portion of one of the heads broken away to expose the interior construction of the machine. Fig. 2 is a sectional elevation of the cylinder and piston. Fig. 3 is a longitudinal section through as y. Fig. 4 is a perspective detail of the block which is placed between the steam and exhaust ports. Fig. 5 is a perspective detail of one of the wings. Fig. 6 is an enlarged perspective detail of the adjustable portion of the block shown in Fig. 4.

In the drawings, A is a cylinder, B the steam-port leading into the cylinder, and C the exhaust-port leading out of it.

D is a piston-head fitted between the plates E, which form the inner heads of the cylinder.

F are wings journaled in bearings formed in the plates E, and designed when closed to fit into recesses a, formed in the piston D.

G is a block inserted between the steamport B and exhaust-port C. This block is shaped substantially as shown in Fig. l, and is shaped so as to fit the periphery of the piston D. The spindles H, which are attached to or form part of the wings F, extend through holes made in the plates E, which holes constitute bearings for the spindles H, and are therefore the bearings of the wings F. At each end of each spindle H, I fit an arm or wiper, I, designed to follow the form of the cams J, attached to or forming part of the outer heads, K, of the cylinder. These outer heads, K, are permanently fixed to the cylinder A, while the inner heads or plates, E, are fixed to the piston D, and revolve with the said piston. A space, Z), is left between the inner and outer heads, as indicated in Fig. 3. W hen the piston D revolves, the wipers I in following the shape of the cam J will cause each wing F to open and fill the space between the piston and the inner circumference of the cylinder the moment that the said wing passes the end of the block G, and when the said wing reaches the other end of the block G, which is at the mouth of the exhaust-port C, the said wing is folded into the recess a, and in that position passes the said block.

In Figs. 1 and 2 one wing is shown in the position it will appear as it reaches the steamport B. It has been folded out by the action of the wiper I against the cam J, and the steam in getting behind it will immediately begin to act on the wing and cause the piston to travel. The pressure of the steam against the wing will hold the said wing sufficiently hard against the inner circumference of the cylinder A to insure the joint to be steamtight, and in order to make steam-tight joints between the ends of the wings F and the inner heads or plates, E, I insert in each end of each wing F an adjustable block, d, provided with a plunger, 6, which fits a hole communicating with a hole, f, made through the wing F, as indicated in Fig. 5. Consequently, when the pressure of steam is against the wing F, it enters the hole f, and, acting against the plungers e, presses the blocks d against the inner heads or plates, E, thereby forming a steam-tight joint.

With the view of insuring a steam-tight joint between the piston-head D and the block G, I insert in the said block an adjustable block, g, having adjustable ends h, which are held against the inner heads or plates, E, by the action of springs 2', while the block 9 is held against the piston-head D by the action of springs j.

It will be noticed that in addition to making an effective rotary engine I have produced an admirable water-meter, as the Wings and the ports are so arranged that the exhaustport is not opened until the steam or supply port is cut off from the said exhaust or discharge port. Consequently the quantity of Water between the Wings will be the same at every revolution.

What I claim as my invention is 1. A cylinder, A, having ports B O, a curved block between them, and an adjustable block in said curved block, in combination with the piston-head D, having plates E fixed thereto, and Wings F, provided With the adjustable blocks (1 and pivoted in said plates, substantially as described.

2. A cylinder, A, having ports 13 and C, separated by the curved block G, in combination with the piston-head D, the adjustable block in said curved block, Wings F, having spindle H, extending through holes made in the plates E, which are fixed t0 the piston D, the adjustable blocks cl in said Wings, and Wipers I, fixed to the spindles H and acting against the cam J, formed on the outer heads, K, substantially as and for the purpose specified.

3. Acylinder, A, having ports B and C, separated by the curved block G, having adjust: able blocks 9 and h, actuated by springs and j and designed to press against the piston D, in combination With the piston-head D, Wings F, having adjustable blocks d arranged within them, as described, and connected to a spindle, H, extending through holes made in the plates E, Which are fixed to the piston D, and Wipers I, fixed to the spindles H and acting against the cam J, formed on the outer heads, K, substantially as and for the purpose specified.
